Best clear night for a while. Quite transparent and still.
M42 for 2017
Got to do it every year – this is the 2017 version. Also trying out my new Revelation x0.75 reducer for the RC8. Seems to work very well for a very reasonable price £69. Spacing should be 80mm +/- 5mm. I managed to get 75mm with my filter wheel and 460EX.

M31 core
Haven’t visited this one for ages. FOV obviously too small to fit the whole galaxy in.
Had to stop after 6 exposures because sky transparency was reducing and dew was becoming an issue.
Dust lanes show up nicely.
